Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizatio

12、ns, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its furthe

13、r maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives

This third edition cancels and replaces the second edition (ISO 7388-3:2013), of which it constitutes a minor revision with the following changes: in the title and in all the text, “retention knobs for shanks of form” was changed to “retention knobs of form”; forms AC and

18、UC have been deleted from the title and from the designation (Clause 6); a footnote was added to Tables 1 and 5.
